Highway bridge diagnostics
Křepelka, Jan ; Suza, Igor (referee) ; Cikrle, Petr (advisor)
This thesis deals with the inspection and construction-technical survey of the highway bridges D2-058..1 and D2-058..2. These structures ale located on the border with the Slovak Republic and were built in 1980. The thesis is focused on the substructure of this long overpass, because of its major failures caused by leaking water. Theoretical part contains information about construction-technical surveys of the bridges, bridges inspections and theory of ultrasound methods. That method has been used in the practical part for identification of the damage extent. Also, material property have been verified and overall condition of the substructure has been evaluated.

Diagnostics of bridge structure
Nápravník, Petr ; Žítt, Petr (referee) ; Láník, Jaromír (advisor)
This bachelor´s thesis deals with construction-technical survey of a highway bridge no. D1-243 across Ripska street at suburbs of Brno. Theoretical part contains bridge terminology, inspections, problematics of prefabricated beams I-73, construction-technical survey and description of laboratory tests. Practical part deals with making of a construction-technical survey, evaluation of construction parts and a summary of results.

The reconstruction design of timber structures of the existing building
Bartlová, Jana ; Šmak, Milan (referee) ; Straka, Bohumil (advisor)
The content of this work was to carry out construction-technical survey of timber structures of the existing building in order to design an appropriate procedure for their reconstruction. The survey showed construction in an unsatisfactory to disrepair, so further work also includes the static calculation of new structures proposed instead of the current. Timber structure in the building has form of staircase, roof and ceiling construction. Newly designed the following types of stairs and roof trusses from which the lower belts are used as ceiling beams. The new proposal also includes possible roofing, roofing options, developed one of them. The work also includes drawings, bill of materials and cost estimate staircase structure and truss. Specialization in the field of civil engineering is represented by drawings of the new truss and passport (view of current state) whole object on parcel ST.74 / 1, land Tišnov (okr.Brno-venkov), the content of which was the basis for this work.

Dendrochronologické datování a stavebně-technický průzkum vodního mlýnu ve Křtinách
Zrůstková, Iva
Thesis tries to reveal more information about wooden historical constructions of the water mill and to assess their condition. The dilapidated water mill in Křtiny began to be gradually restored after transfer to a private ownership. Only a few records was known about the history of this interesting building. The aim of the thesis was dendrochronological dating and anatomical identification of the wooden constructions, completed by searching all available literature sources concerning the studied buildings. The priority of building-technical survey was to determine the degree and extent of damage of the individual wooden elements using visual assessment and non-destructive methods. Dendrochronological dating shows that the roof construction was build after 1913. The wooden constructions on the 1st floor and the 2nd floor were dated to the end of the 1920s and the beginning of the 1930s. Plank flooring was dated to the period after 1863. The oldest surviving construction located in the adjacent shed was dated to 1781/1782. The results of building-technical survey shows relatively good condition of wooden elements, however, the ceiling on the 3rd floor should be checked in regular intervals where water leaking was observed. Given that almost no historical sources was found the work brought new information about the development of the water mill. Moreover, necessary preventive inspections were recommended to preserve the historic value of the building.

Priezkum a dokumentacia krovu kaštiela
Kirner, Marek
This thesis is focused on a survey of roof structure of the Jablonica castle and a technical documentation of the current object state. In consideration of non-existing documentation, it was necessary to provide a precise surveying, realized by 3D scanning. The next step was inspection of roof structures itself, portrayed in the documentation of actual state. Also rated according to structural damage, and suggested preventive actions, according to extensive wood-destroying insects and rot defects and damage, due to contact with rainwater. Based on founded informations in each roof structures remediation procedures and reconstruction steps were suggested. This thesis and following documentation can provide information of roof structures conditions, next steps in realization of remediation and reconstruction, or as a basis for more specific inspection.

Stavebně-technický průzkum krovové konstrukce kostela sv. Františka Serafínského v Lipníku nad Bečvou
Hašová, Jiřina
The subject of this thesis was to make a constructive-technical research on timbers of St. Francis Seraph church in Lipník nad Bečvou. This church is registered into national list of sights as a sight number 29870/8-485. It is a Gothic-Renaissance building dating from 1590-1593. The roof above the cancel and nave consists of free floors dollar beams, queen post and truss frames. The aim was to reveal biotic damage to individual elements of timbers and to determine the extent of the damage. The evaluation of timbers was based on sensory and devices research. The roof was attacked mostly house longhorn beetle, rotting, especially in places where there was high humidity. The damage was caused mainly on wall beams and camping piece of tie beams. Based on achieved results we suggested remedial measures which are intended to preserve the built of wood, which is in a satisfactory condition. This thesis also deals with dendrochronological dating where we tried to determine the age of construction by dendrochronological analysis. The roof above the nave and chancel was dated to the period 1769-1771. Thesis is completed with anatomical determination of forest species which were used in individual parts of timbers. The results provide information for planned reconstruction of monument considering its current constructive - technical condition.

A Typology of Historic Roof Trusses
Navrátil, Miroslav
When surveying and documenting historic trusses, it is possible to determine the time they were constructed just by assessing the type of structure used and some selected hand-crafted details. This chronological typology differs from the current state of knowledge which relies predominantly on descriptions of load-bearing structures. The new typology significantly adds to the possibilities of historical surveying, and opens new ways for presenting roof trusses as historical monuments. It also adds value by helping us to learn more about wood-crafting methods and techniques.
